Specification of Letters Patent.

Patented Nov. 18, 1919.

Application filed August 20, 1919. Serial No. 318,830.

To all whom it may concern Be it known that 1, WILLIAM F. Bossnn'r, acitizen of the United States, residing at Utica, in the county of Oneidaand State of New York, have invented certain new and useful improvementsin Apparatus for Adjusting Switch-Points; and I do hereby de clare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters and figures of reference marked thereon, which form apart of this specification.

This inventionrelates to new and useful improvements inattachments toapparatus for operating switch points, and consists essentially in theprovision of means espe cially adapted to the type of device covered byLetters Patent #1,136,767, granted to me upon April 20, 1915.

It has been found from practice that the steel end caps of the typereferred to, and which are made of hard drawn steel and secured to theswitch adjusters, frequently be come inefficient during severe coldweather, and the torches which are commonly used for thawing snow andice about the adjuster takes the temper out of the end caps, and as aconsequence they become loose and slide upon the rods and nuts, and donot afford the desired protection.

The present invention consists in the provision of an end cap ofsubstantial weight and made preferably of malleable iron and which maybe easily and quickly attached to the adjuster when in operation.

The invention comprises various other details of construction,combination and arrangement of parts which will be hereinafter fullydescribed, shown in the accompanying drawings and then specificallydefined in the appended claims.

My invention is illustrated in the accompanying drawings which, with thenumerals of reference marked thereon, form a part of this application,and in which:

Figure 1 is a central longitudinal sectional view through the casing inwhich the adjustable switch operating rods pass, the attachments beingshown in section.

Fig. 2 is a sectional view on line 22 of Fig. 1.

Fig. 3 is a detail view in elevation of a modified form of theattachment comprising two complemental sections adapted to be connectedby bolts.

Fig. 4: is a View in elevation showing a different modification of theattachment, in which a stud joint connection is provided between theparts, and

Fig. 5 is a still difierently modified form in which the parts haveknuckle joint connection.

Reference now being had to the details of the drawings by numerals:

1 designates a casting having a flanged portion 2 apertured for thereception of the bolts 3 forming means whereby the switch point throwingbar 4 may be held to said casting. A casing 5 which is hollow isprovided with a central contracted portion and each end of the casingflares, as shown, at 6 forming a cup shaped chamber, the inner surfacesof which are concaved as at 7 and form abutment surfaces. A rod 8circumferentially threaded passes through the casthrowing apparatus (notshown) is adapted to be secured whereby a longitudinal movement may beimparted in one direction or the other to said rod. Cylindrical nuts 9and 12 are mounted upon said rod and have their inner ends convexedadapted to conform to and bear against the concaved surfaces 7 in thechambered portions of the casing and the circumferences of the outerends of said nuts are squared as at 10 affording means to be gripped bya wrench or other tool to facilitate turning the nut upon the rod. Jamnuts 11 are mounted upon the threaded rod and adapted to bear againstthe nuts 9 and 12 to hold the same from loosening.

Caps designated respectively by numerals 15 and 16, made preferably ofmalleable iron, are made up of two sections and connected together bymeans of a pivotal pin 18. Each of said sections has a lateral flangewith a concaved groove upon its inner surface adapted to engage over abeading 19 upon the casing 7 and at points diametrically opposite thepivotal pin and each end of a cap section has a laterally extending lug20 apertured for the reception of a bolt 21 adapted to hold the twosections in clamped relation with the casing, and upon said bolt a nut22 is mounted and. preferably intermed ate the nut and the adjacent lugof a section 18 a nut locking member 23, the ends of whlch are adaptedto bite into the adjacent faces of the nut and locking member to holdthe nut from loosening.

A washer ii is placed intermediate the sections of the end of the casingto provide a close fit around the adjusting nuts and have the sameinside diameter as the outside diameter of the adjusting nuts, theoutside diameter ,of the washer being semewl at larger than the diameterof the chambers in the adjusting casing and thereby afiiording means forprotecting the chamber against the accumulation of snow, ice and foreignmatter, and at the same time providing a means whereby any binding ofthe switch adjusting rods, caused by the creeping of the rails, may beobviated, this being eltected by reason of the adjusting nuts being ofconsiderably smaller diameter than the chamber of the adjuster.

In Fig. 3 of the drawings 1 have shown a modified form of my two-partcap, in which the sections 26 and 27 are of complement-a1 form and eachprovided with oppositely disposed lugs 28 in alinement with each otherand provided with registering apertures for the reception of fasteningbolts 29, instead of the use of a pivot, as shown in Fig. 2.

In Fig. 4 I have shown a modified form in which the section 30 isprovided with a stud 31 upon a lateral. project-ion 32 at one end ofsaid section and which is adapted to engage over an integral hook formedintegral with the section 34:. and forming a hinged joint, while theopposite ends of said section are provided with lugs 35 and registeringapertures for the reception of the bolt.

In Fig. 5 is illust 'ated a still dili'erently modified form of theinvention, in which the section 36 is provided with an integral hook 37adapted to interlock with a hook 38 upon the section 39 forming aknuckle joint, the opposite ends of the section being provided with theusual apcrtured lugs 40 for the reception of a bolt.

By the provision of a cap made up of sections as shown and described,and which is of substantial weight and made of malleable iron, same maybe easily attached to the adjusters and provide a. strong and solidattachment to obviate the objections occasioned by caps which haveheretofore been used with the form described in my former referred topatent, the sections being easily replaced when desired.

What I claim to be new is:

l. Attachments for casings for apparatus for adjustin switch points onrailways, consisting or" curved sections for attachment about thecasings, and means for holding the sections together about the casings,

Attachments for casings tor apparatus for adjusting switch points onrailways, comprising curve-d sectional cans each having a concavedgroove in its inner face, and means for fastening the sections together.

3. Attachments :lor casings for apparatus for adjusting switch points onrailways, caps made up of two complemental sections, each having alateral flange which s provided with a cylindrical groove upon its innersurface tapted to engage over the end of a. casing, and means forholding the sections together.

4t. Attachments "tor casings for apparatus for adjusting switch pointson railways, caps made up of complemental sect-ions to engage'over theend of a casing, the corresponding ends of the sections being pivoted,and a bolt connecting the opposite ends at points diametricallyopposite.

In testimony whereof I hereunto affix my signature.
